People who eat at home most of the time have better nutrition than those who go out to eat , a recent study shows. Cornell University professors Lana Hall and Karen Bunch interviewed(面試,接見) 3900 people in the survey. “People who eat less than 30 percent of their food away from home eat the most nutritiously,” they said.
“In general, Americans don’t have nutrient, except for iron and calcium,” they reported. They have the opposite problem——over—consumption(過度消耗), especially of fat.
The food at many fast food restaurants is often low in vitamins. “People who eat more than 30 percent of total calories away from home eat foods that are generally low in nutrients per calorie,” the professors said. More calories and enough nutrient intake(吸收) are required to achieve.
One of the major health risks(風(fēng)險) is eating too much fat. The professor found than fat consumption became greater as income(收入) went up. It also went up in houses where the female worked. This is probably because these people eat more highly processed (加工的)foods.

A.Eat out as many times as possible
B.Eat at home as many times as possible
C.Eat foods with a lot if iron, calcium and fat
D.Eat more highly processed foods

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores(胚芽). Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.
小題1:Plants can make food from______.
A.flower, water and airB.water, sunlight and air
C.a(chǎn)ir, water and soilD.a(chǎn)ir, sun and light
小題2:The main idea of the first paragraph is that ______.
A.plants are important for life
B.plants cannot grow without air
C.there are many plants in the world
D.we can not live without water
小題3:What can we infer(推斷) from the passage?
A.Of all living things animals are most important
B.Spores are seeds
C.All fruits of flowering plants have seeds
D.Without plants, man will die out

It is always hard for a small fish to live in a big pond. Pluto's recent departure from the classical planet family clearly proves that size really matters.
Astronomers voted on August 24 to create the first scientific definition of the word planet, and Pluto obviously didn't make the cut. It turned out to be only a "dwarf planet" (矮行星). After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a "planet" at a conference of the international Astronomical Union (IAU). According to the definition, a planet must have a clear neighborhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptune's. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptune's gravity when the two planets get closer.
According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight "classical planets," together with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The debate over Pluto's status started in 1992. After an advanced telescope was sent into space, astronomers started find a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto.
It seems that even if the IAU had kept Pluto's status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around. More dwarf, planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets.
小題1:According to the passage, Pluto is          .
A.a(chǎn) planet which has a clear neighborhood around its orbit
B.a(chǎn) satellite of Neptune which was discovered in 1930
C.the smallest planet in the solar system
D.a(chǎn) planet which has an orbit around the sun
小題2:The sentence "It is always hard for a small fish to live in a big pond" quoted in the beginning of the passage is used to           .
A.tell us a small fish can hardly survive in the big pond
B.tell us the size of an object really matters
C.mean that a small planet can hardly exist in the solar system
D.explain the disappearanee of Pluto in the solar system
小題3:From the last paragraph we can infer that if IAU kept Pluto's status as a planet, the number of planets in the solar system would be        .
A.eightB.nineC.less than nineD.more than nine
小題4:Which of the following statements is NOT true aceording to the passage?
A.According to definition of a "planet", if Pluto were bigger it would not have left the classic planet family.
B.It's quite possible for dwarfs to lose if they compete with big men
C.Pluto has a special orbit which overlap with Neptune's, because it is so small as to be attraeted by Neptune's gravity when the two planets get closer
D.A "dwarf planet", which can not be a satellite without a clear neighborhood around its orbit, should have an orbit around the Sun.

   In many parts of the world, cars play an important role in daily life and many societies would not exist without them. So the idea that in 20 years’ time, no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean much saving, no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis , who leads the research team, these predictions are based on the rising cost of the car culture, which has blocked up our cities, polluted our air , and caused more deaths than both world wars put together.
Davis says, cars will be fitted with some intelligent devices to regulate the distance between one car and another. The car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.
By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen. And by 2020, cars will travel in convoy, linked to each other electronically. Cars will be connected by an electronic tow bar to the car in front to form “road–trains”. “The front vehicle in such a train burns the normal amount.” says Davis. “But all the others in the train would burn about ten percent of the normal amount, and so produce about ten percent of the pollution.”
小題1:We know from the passage that governments and car manufacturers _______
A.do not believe the prediction that no one will own cars by 2020
B.a(chǎn)re devoted to the technological revolution in car industry
C.consider the predictions seriously
D.have put the super-intelligent car into mass production
小題2:Which of the following will be the characteristic of the cars of 2020?
  1. The car will speed up out of control.
  2. We will own as many cars as we want.
  3. All cars will be driven by computers.
  4. Cars will produce more pollution than present ones.
小題3:The leader of the research team believes that the present car culture should change because_________.
  1. cars play a very important role in daily life
  2. many societies would stop functioning without cars
  3. cars should not be owned by one individual
  4. it causes many deaths to human society
小題4:The expression closest in meaning to the phrase “in convoy” in the last paragraph is________.
A.in lineB.sidelongC.side by sideD.shoulder to shoulder
小題5:What will happen if cars are joined to each other electronically in 2020?
  1. Motorists will get a clear view of the road.
  2. The weather condition will not have effect on motorists.
  3. There will be less pollution caused by car.
  4. All trains will burn less fuel than present.

For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).
Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安裝) a large number of internet-connected features in machines in an effort to make them “smart”.
Last year, it was a refrigerator that tweeted. This year, it’s Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.
The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners is at work or on the bus.
Samsung says it’s not just something new — the app connection actually has some practical uses.
“If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.
The company also says that with electricity rate(電價)varying depending on the time of day, more control over when the machines are used can help save money.
Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.
小題1:What can be inferred from the common response of the attendees at the CES?
A.The machine will be a big success.
B.their wives like doing the laundry.
C.The machine is unrelated to their life.
D.This kind of technology is familiar to them.
小題2:What can we learn about the new laundry machines?
A.They can tell you when your clothes need washing
B.They can be controlled with a smartphone
C.They are difficult to operate
D.They are sold at a low price
小題3:We can conclude form Samsung’s statements that ___________.
A.the app connection makes life easier
B.it is better to dry clothes in the morning
C.smartphone can shorten the drying time
D.we should refresh clothes back at home
小題4:What is the main idea of the last paragraph?
A.The laundry should be frequently checked
B.Lazy people like using such machines
C.Good technologies also cause problems
D.Television may help do the laundry.

The day after news broke of a possible revolution in physics ——particles (粒子) moving faster than light ?a scientist leading the European experiment that made the discovery calmly explained it to a standing-room- only crowd at CERN.
The physicist, Dario Auterio, did not try to explain what the results might mean for the laws of physics, let alone the broader world.After an hour of technical talk, he simply said, "Therefore, we present to you today this difference, this unusualness."
But what unusualness it may be.From 2009 through 2011, the massive OPERA detector (探測器)buried in a mountain in Gran Sasso, Italy, recorded subatomic particles called neutrinos ( 中微子) arriving faster than light can move in an empty space.The neutrinos generated at CERN are hardly detectably early.If confirmed, the finding would throw more than a century of physics into disorder.
"If it's correct, it's phenomenal." said Rob Plunkett, a scientist at Fermilab, the Department of Energy physics laboratory in Illinois."We'd be looking at a whole new set of rules" for how the universe works.Those rules would bend, or possibly break, Albert Einstein's special theory of relativity, published in 1905.Basical at the time, the theory tied together space and time, matter and energy, and set a hard limit for the speed of light, later measured to be about 186, 000 miles per second.
No experiment in 106 years had broken that speed limit.Physicists expect strict study to follow, which OPERA and CERN scientists welcomed.
Fermilab operates a similar experiment, called MINOS, that shoots neutrinos from Illinois to an underground detector in Minnesota.In 2007, MINOS discovered a just detectable amount of faster than-light neutrinos, but the permissible difference of error was too big to "mention" , Plunkett said.
Fermilab scientists will reanalyze their data, which will take six to eight months.In 2013, the MINOS detector, now offline, will restart after an upgrade.It could then offer confirmation of the results.
小題1:Why are the European scientists not sure about the results of the experiment?
A.Because they are so unexpected.
B.Because the scientists do not believe them.
C.Because the scientists are careful and calm.
D.Because they are against the present law of physics.
小題2:The underlined word " phenomenal" in the fourth paragraph has the closest meaning to          .
A.a(chǎn)mazingB.a(chǎn)ttractiveC.embarrassingD.sensitive
小題3:The best title for the passage may be _____.
A.Are the laws of physics in disorder?
B.Particles faster than light; Revolution or mistake?
C.Faster than light measurement: right or wrong?
D.Is Einstein's theory still right today?
小題4:What may be discussed in the paragraphs to follow?
A.Different opinions about the experiment.
B.How Albert Einstein's theory developed.
C.The new rules for how the universe works.
D.How Fermilab scientists will reanalyze their data.

Have you ever suddenly felt that someone you knew was in trouble—and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感覺知覺).
ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example—one of hundreds of dreams that have come true:
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more."
Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
小題1:According to the passage, the author believes that the sixth sense is_________.
A.in existenceB.imaginativeC.not real D.impossible
小題2:By studying ESP, scientists may get to_________.
A.learn how people tell lies
B.know more about human dreams
C.know more about human mind
D.learn how strange things happen
小題3:In the last paragraph the underlined word "coincidences" probably means ____.
A.things that may not happen
B.things that happen in a dream
C.things that must happen
D.things that happen by accident
小題4:This article is mainly about_________.
A.the human dream B.the sixth sense
C.the human mind D.a(chǎn) crowded bus

Sometimes people add to what they say even when they don’t talk. Gestures are the “silent language” of every culture. We point a finger or move another part of the body to show what we want to say.It is important to know the body language of every country or we may be misunderstood.
In the United States,people greet each other with a handshake in a formal introduction.The handshake must be firm.If the handshake is weak,it is a sign of weakness or unfriendliness.Friends may place a hand on the other’s arm or shoulder.Some people,usually women,greet a friend with a hug(擁抱).
Space is important to Americans.When two people talk to each other,they usually stand about two and a half feet away and at an angle,so they are not facing each other directly.Americans get uncomfortable when a person stands too close.They will move back to have their space.If Americans touch another person by accident,they say “Pardon me” or “Excuse me”.
Americans like to look at the other person in the eyes when they are talking.If you don’t do so,it means you are bored,hiding something,or are not interested.But when you stare at someone,it is not polite.
For Americans,thumbs-up means yes,very good,or well done.Thumbs-down means the opposite.To call a waiter,raise one hand to head level or above.To show you want the check,make a movement with your hands as if you are signing a piece of paper.It is all right to point at things but not at people with the hand and index finger(食指).Americans shake their index finger at children when they scold them and pat them on the head when they admire them.
Learning a culture’s body language is sometimes confusing(使糊涂的).If you don’t know what to do,the safest thing to do is to smile.
小題1:From the first paragraph we can learn that ________.
A.gestures don’t mean anything while talking
B.gestures can help us to express ourselves
C.we can learn a language well without body language
D.only American people can use gestures
小題2:If you are introduced to a stranger from the USA,you should _______.
A.greet him with a hug
B.place a hand on his shoulder
C.shake his hand firmly
D.shake his hand weakly
小題3:In the United States,people often ________.
A.show their friendship by touching each other
B.show their friendship by glancing at each other
C.say “Pardon me” to each other when they are talking
D.get uncomfortable when you stand close to them
